Embodiment 3

Figure 7 is an enlarged schematic view of the portion B in Figure 6; based on the above embodiment, with continued reference to Figures 1-3, 6-7, it is known that when the landing gear 5 is mounted on the landing gear base 3, Landing gear 5 The stable reliability of the installation, the antenna mounting bracket is further arranged to include a landing gear quick release latch 8 connected to the landing gear base 3 for locking the connection state of the landing gear 5 and the landing gear base 3.

The landing gear quick release buckle 8 in this embodiment can be detachably connected to the landing gear base 3, specifically, can be realized by means of a buckle, or the landing gear quick release buckle 8 and the landing gear can also be used. The base 3 is provided as a screw connection or a pin connection, as long as the quick release effect of the landing gear quick release buckle 8 can be achieved; in addition, the landing gear quick release buckle 8 can also be used for the landing gear 5 and the landing gear base. The connection state of the seat 3 is locked. Specifically, the landing gear quick release buckle 8 can be set to include:

The clamping mechanism 801 is connected to the landing gear base 3 and symmetrically disposed on both sides of the landing gear 5 for clamping/releasing the landing gear 5;

A control mechanism 802 is coupled to the clamping device for controlling the clamping device.

The specific shape and structure of the clamping mechanism 801 are not limited, and those skilled in the art can set according to specific design requirements. For example, the clamping mechanism 801 can be configured as a clip-type structure, that is, the clamping mechanism 801 includes symmetry. The clips disposed on both sides of the landing gear 5 can clamp the landing gear 5 when the distance between the clips on both sides is reduced, and the landing gear 5 can be loosened when the distance between the clips on both sides is increased; or, The clamping mechanism 801 is configured to include: a first hoop 8011 and a second hoop 8012 connected to the first hoop 8011, the first hoop 8011 and the second hoop 8012 are relatively movable;

When the gap between the first hoop 8011 and the second hoop 8012 becomes larger, the clamping mechanism 801 releases the landing gear 5; when the gap between the first hoop 8011 and the second hoop 8012 becomes smaller, the clip The tightening mechanism 801 clamps the landing gear 5.

It should be noted that the first hoop 8011 and the second hoop 8012 have the same shape and structure. Since the first hoop 8011 and the second hoop 8012 can move relative to each other, the first hoop 8011 and the second hug can be The hoop 8012 is connected by an elastic member, and the first hoop 8011 and the second hoop 8012 can be relatively moved by the elastic force and the restoring force of the elastic member; at this time, when the elastic member is in a compressed state, the first hoop The gap between the 8011 and the second hoop 8012 becomes smaller, that is, the first hoop 8011 and the second hoop 8012 are in a close state, and when the first hoop 8011 is close to the second hoop 8012, it is located at two The space between the side hoops is also reduced, thereby achieving the clamping mechanism 801 clamping the landing gear 5; when the elastic members are in the extended state, the gap between the first hoop 8011 and the second hoop 8012 becomes Large, that is, the first hoop 8011 and the second hoop 8012 are in a state away from each other, due to the When the hoop 8011 is away from the second hoop 8012, the space between the hoops on both sides is also increased, thereby realizing the clamping mechanism 801 to release the landing gear 5.

Of course, the relative movement between the first hoop 8011 and the second hoop 8012 can be implemented by other methods in the art. Among them, the first hoop 8011 and the second hoop 8012 can be preferably used. It is arranged to be connected by pulling the shaft, and the first hoop 8011 and the second hoop 8012 are axially movable along the pulling shaft.

Specifically, the first hoop 8011 and the second hoop 8012 are sleeved on the pulling shaft, and referring to FIG. 7, the first hoop 8011 is adjacent to the fuselage connecting portion 9, and the second hoop 8012 is adjacent to the control mechanism 802. Therefore, when the control mechanism 802 abuts the second hoop 8012, a urging force is generated, which can cause the second hoop 8012 to move in the direction of pulling the axial first hoop 8011, thereby making the second The gap between the hoop 8012 and the first hoop 8011 becomes smaller. When the first hoop 8011 is close to the second hoop 8012, the space between the hoops on both sides is also reduced, thereby achieving clamping. The mechanism 801 clamps the landing gear 5; when the control mechanism 802 is separated from the second hoop 8012, the second hoop 8012 will move in a direction away from the first hoop 8011 along the pulling axial direction due to the withdrawal of the driving force. Therefore, the gap between the second hoop 8012 and the first hoop 8011 is increased. When the first hoop 8011 is away from the second hoop 8012, the space between the hoops on both sides is increased. The clamping mechanism 801 is realized to release the landing gear 5; thereby effectively achieving the passing of the clamping machine The operation of the structure 801 to clamp or loosen the landing gear 5 ensures stable reliability of the connection between the landing gear 5 and the landing gear base 3.

In addition, the specific shape and structure of the control mechanism 802 is not limited in this embodiment, and those skilled in the art can arbitrarily set the control mechanism 802 according to the function of the implementation. Preferably, the control mechanism 802 can be configured to include:

The cam 8023 includes a first wheel portion 80231 and a second wheel portion 80232 connected to the first wheel portion 80231, and the first wheel The inner diameter of the portion 80231 is larger than the inner diameter of the second wheel portion 80232;

When the first wheel portion 80231 of the cam 8023 abuts against the clamping mechanism 801, the clamping mechanism 801 clamps the landing gear 5; when the second wheel portion 80032 of the cam 8023 contacts the clamping mechanism 801, the clamping mechanism 801 Loosen the landing gear 5.

The first wheel portion 80231 is integrally formed with the second wheel portion 80232. It should be noted that the cam 8023 has an irregular elliptical structure, that is, the inner diameter of the first wheel portion 80231 is larger than the second wheel portion. The inner diameter of the 80232, and the cam 8023 is for contacting the second hoop 8012 in the clamping mechanism 801, the cam 8023 can be rotated along the rotating shaft 8021, and thus, when the cam 8023 is rotated to the first wheel portion 80231 and the clip When the fastening mechanism 801 abuts, that is, the first wheel portion 80231 at this time abuts against the second hoop 8012, since the size of the first wheel portion 80231 is large, a driving force is generated, which can promote the driving force. The second hoop 8012 moves in the direction of pulling the axial first hoop 8011, so that the gap between the second hoop 8012 and the first hoop 8011 becomes smaller, thereby achieving the clamping mechanism 801 clamping the landing gear 5; Similarly, when the cam 8023 is rotated until the second wheel portion 80232 is in contact with the clamping mechanism 801, since the second wheel portion 80232 is small in size, the driving force for promoting the movement of the second hoop 8012 is evacuated. At this time, the second hoop 8012 moves in a direction away from the first hoop 8011 along the pulling axial direction, so that the gap between the second hoop 8012 and the first hoop 8011 becomes larger, thereby realizing the clamping mechanism 801 loose. Open the landing gear 5.

Specifically, in order to facilitate the rotation of the control cam 802 along the rotating shaft 8021, the control mechanism 802 further includes a handle 8022 coupled to the cam 8023 for driving the cam 8023 to rotate along the rotating shaft 8021.

The handle 8022 in this embodiment may be connected to the cam 8023 through a connecting member, and the connecting member may be a screw, a bolt, a stud or an adhesive, etc., wherein, preferably, the handle 8022 and the cam 8023 are integrally formed. The connection can effectively ensure the stable reliability of the connection of the handle 8022 and the cam 8023. When the user moves the position of the handle 8022, the moving handle 8022 can drive the cam 8023 to rotate along the rotating shaft 8021, thereby ensuring the rotation of the cam 8023. The convenience and reliability of the control further improve the practicality of the antenna mounting bracket.
